Bag that can be cross body or backpack

[perfectlybroken]

I bought this one thinking what an inspired idea it was. I like cross body bags but if it's heavy/I'm walking a long way prefer a backpack.

BUT it looks quite cheap (because it is), I thought the buckles were silver coloured but actually they are gold which spoils it.

Does anyone know of any other similar bags?

Ffjallraven does one I think. Tote or backpack. It's quite unsubstantial compared to their other bags though

Thanks I'll have a look.
